I appreciate the info and the post. Unfortunately I'm am also a recipient of a cracked windshield (June 27, 2016). It happened while driving 55mph in the slow lane (RH side) of a four lane paved road while on our Nebraska summer family road trip. From the very start I set out to be supper careful by not following trucks closely or vehicles without mud flaps, etc. As fate would have it I now have a 6" crack that has emanated from a single rock ding. I haven't bothered to replace it yet till I know there is an very good product to protect windshields. I considered putting Clearplex on the windshield, when I got the car wrapped with XPEL, but didn't because the installer mentioned there wasn't a big enough piece available for a Model X; wasn't totally happy with it due to the wiper scratching issue over time; and propensity for lifting on the edges. On the plus side, I have comprehensive insurance with a $1k deductible. If anyone finds a good film for windshields, please post it.
